For future reference: On the inside crown of most every helmet liner made in WWII, is a manufacturers identification stamp. Below are graphics of what each stamp should look like along with the manufacturers name:

 

First up, a low pressure liner manufacturer:

Hood Rubber Company, Inc.

Watertown, Massachusetts

 

Identified by a silver "HR" in the crown

Great topic. This should be pinned. I read somewhere where some of the INLAND stamps were stamped backwards, frontwards, and sometimes both on the same liner. :think:

Here's a double stamp image of an Inland mold that made it's way to Firestone where their stamp was superimposed over the old Inland stamp.

On the Hawley helmet liners that were sub-contracted to General Fibre Co. you'll also find a simple 'G' stamped somewhere near the crown. This is an image of an actual 'General' stamp.

Thanks for the liner manufacturer identification stamp information. This really helps to tell who made my liners. Is there liner identification stamps for liners used in KOREA and VIETNAM? I have not found any.

Capac is definitely the most dangerous one if you collect wwII stuff.

 

I got fooled once and it immediately went back.

 

Wouldn't buy them anymore.

 

I do have a Seaman liner if you guys ever need pics on that one.

 

Cheers
